Part 14 of 20: Heat

(A few weeks later)

Papyrus and Fell had already left to do their jobs as a sentry and a royal guard. They wouldn't be back until late afternoon.

Lust lay on Papyrus's bed, leashed to the wall. He had woken up to a persistent throbbing in his soul. His soul now pulsed brightly and painfully against his ribcage.

"H-hah.." A light sheen of sweat appeared on his forehead. He curled up into himself, shuddering.

Why did his heat have to come today? It was making him feel itchy and uncomfortable. He wanted, no, needed, someone to touch him.

He summoned his soul in front of him, bathing himself in its light. Running a finger lightly over the surface, he shivered violently. Oh, that felt so good. He panted, continuing to lightly probe his soul.

He put it back into his ribcage. He could probably deal with this heat until the brothers got back since they  wouldn't be back for hours.

Suddenly, Lust heard the sound of someone teleporting into the room. "Hey Lust." A familiar voice said.

Crap. He'd forgotten that Fell came in during work to talk to him sometimes. He claimed sentry duty didn't really have anything to do, so instead, he visited Lust and chatted with him.

Lust would even say they had become almost friends, getting to know each other better. They were still alternate versions of the same person, even if they were very different.

But today was really not a good day. Why did he have to come visit him today out of all days!? He probably could've lasted until they came back, but now that Fell was here, he could feel his body rebelling against him. He wanted Fell to touch him, kiss him, fuck him..

NO.

Lust slammed his eye-sockets shut, groaning. He gripped his arms so hard, he could feel the bone creak.

Fell stared at Lust curled up into a ball on the bed. "Uh, are you ok?" He stared apprehensively at Lust.

"I'm fine." Lust said through gritted teeth. He continued to stay curled up into a tense ball.

Fell paused, concern flickering across his face, but he quickly hid it behind a detached mask. "Um ok. Can I help you in any way?"

Oh God. The implications of that statement was making Lust go insane. He gasped, then bit his hand to stifle the noise.

He just wanted Fell to go away, but the presence of having another monster here was driving him crazy. He didn't think he could control himself.

"C-Could you come here~?" Lust's voice sounded sexual, even to himself. Fell stared at Lust with an unreadable expression.

After a pause, he walked over to the side of the bed. "Ok, now wha-"

He was cut off as Lust suddenly grabbed his hand, pulling him onto the bed. He slammed Fell into the wall next to the bed, then climbed onto his lap, facing him. Lust smiled flirtatiously, his tongue flicking across his teeth.

Fell stared up at Lust with a flushed face. Lust wasn't even wearing pants, because Papyrus preferred him not to. All he was wearing was a baggy t-shirt and knee-length socks.

Lust smiled down at Fell, then pulled his own shirt over his head. Now, he sitting, practically naked, on Fell's lap. "U-uhh.." Fell stuttered, his eye-sockets wide.
